The Nuances of Health Literacy, Nutrition Literacy, and Food Literacy.

Health literacy, defined as the ability to access, understand, and use health information, has been identified as an international public health goal. The term nutrition literacy has emerged as a distinct form of health literacy, yet scholars continue to reflect on constituent skills and capabilities in light of discussions regarding what it means to be food literate and health literate. This viewpoint argues that a comprehensive conceptualization of nutrition literacy should reflect key elements of health literacy and food literacy constructs. Nutbeam's tripartite model of health literacy is employed to explore competencies that are likely to facilitate healthy food relationships.
